Benefits of technology

[0020]The object of the present invention now consists in specifying a medical instrument, which is particularly suited to use with a phase contrast imaging and is characterized in particular compared with conventional medical instruments by an improved visibility in a differential phase contrast image and / or dark-field image. The object of the present invention further consists in specifying a corresponding x-ray recording system.

Problems solved by technology

If the medical instruments proven in use with classical x-ray technology are used with a phase contrast imaging, the achieved results, in particular with respect to the display quality of the obtained x-ray images, are often inadequate.

Embodiment Construction

[0053]FIG. 2 by way of example shows a schematic medical instrument 1 having a number of components which enable a good x-ray dark-field image representation. The medical instrument 1 is embodied as a medical catheter. A medical catheter is understood to mean in particular a tubular or rod-type device with a length of approx. 0.3 to 1.5 m and a diameter of approx. 1 to 20 mm, which can be introduced into a human or animal body. Furthermore, a medical catheter can include integrated instruments which can be introduced by way of working channels, e.g. micromechanical devices, such as small forceps or grippers, with which examining or intervening procedures can be performed. The medical instrument 1 includes a tubular base body 21, which has an opening 22. A first subarea 23 of the tubular base body 21 is embodied with a layer of sponge-type material, so that the surface of this region has microscopically small, porous openings, which can be effectively displayed, in particular in a co...

Abstract

A medical instrument is provided for use with a phase contrast imaging. The medical instrument includes at least one component, which has a strong small angle scattering of x-rays. Furthermore, a corresponding x-ray recording system with phase contrast imaging for recording an examination object may include such a medical instrument.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority of German Patent Office application No. 102013214388.5 DE filed Jul. 23, 2013. All of the applications are incorporated by reference herein in their entirety.FIELD OF INVENTION[0002]The present invention relates to a medical instrument for use with a phase contrast imaging. Furthermore, the present invention relates to a corresponding x-ray recording system with phase contrast imaging.BACKGROUND OF INVENTION[0003]The differential phase contrast imaging or in short phase contrast imaging represents an imaging method which has received a lot of attention over the last few years particularly in the Talbot Lau interferometer arrangement. The publication by F. Pfeiffer et al., “Hard X-ray dark-field imaging using a grating interferometer”, Nature Materials 7, pages 134 to 137 describes that with the aid of an interferometric structure, which consists of a conventional x-ray tube, three gratings and an x-ray det...
